  • Which diet has the smallest carbon footprint?
    The health benefits of the Mediterranean diet are well-known. As well as being healthier, a recent article concludes that the menu traditionally eaten in Spain leaves less of a carbon footprint than that of the US or the United Kingdom. The consequences of climate change range from species extinction to sea-level increases and the spread of diseases. For this reason, researchers have been struggling for years to alleviate its effects, even limiting the pollution caused by food consumption.
  • France passes law to promote green roofs
    Environmentalism is fast becoming a top concern in France – a rooftop concern, to be precise. Excitingly, the nation has just passed new legislation that will require all upcoming commercial construction projects to feature either green roofs or solar panels above their top floors.
  • How NASA is planning on diverting an asteroid
    NASA has decided to pluck a small boulder off an asteroid and bring it back to the vicinity of Earth, rather than bag up an entire asteroid, agency officials in charge of the Asteroid Redirect Mission (ARM) announced today.The $1.25 billion mission, which is planned to launch in December 2020, would send a robotic spacecraft for a rendezvous with an asteroid in 2022. After touching down on the asteroid’s surface, the spacecraft would snatch a boulder several meters across. The spacecraft would then orbit the asteroid for up to 400 days, testing out an idea for defending Earth from a catastrophic asteroid impact: using the spacecraft’s own gravitational field to subtly alter the asteroid’s orbit. Next, the spacecraft would bring the snatched rock back to Earth’s vicinity in 2025. Finally, as part of preparations for a possible mission to Mars, astronauts would visit and examine the rock for some 25 days, using the planned Orion spacecraft to make the trip.
  • Fish face pollution a mile deep
    Deep-water marine fish living on the continental slopes at depths from 2,000 feet to one mile have liver pathologies, tumors and other health problems that may be linked to human-caused  pollution, one of the first studies of its type has found. The research, conducted in the Bay of Biscay west of France, also discovered the first case of a deep water fish species with an “intersex” condition, a blend of male and female sex organs. The sampling was done in an area with no apparent point-source pollution, and appears to reflect general ocean conditions.
  • How to reduce your car's impact
    As we all know, cars, trucks, and other motor vehicles aren’t the best friends of the environment. However, for many of us it’s simply not practical to depend strictly on mass transportation or make the switch to an all-electric vehicle. As a green-thinking member of society, where does that leave you? What should your stance be on driving with relation to sustainability?
  • Was there ever life on Mars?
    Did Mars ever support life?  This question has intrigued us for centuries!  We have had spacecraft on Mars for quite a while poking and analyzing soil and rocks and taking photos.  Now NASA has new data which help answer these questions.A team using the Sample Analysis at Mars (SAM) instrument suite aboard NASA's Curiosity rover has made the first detection of nitrogen on the surface of Mars from release during heating of Martian sediments. The nitrogen was detected in the form of nitric oxide, and could be released from the breakdown of nitrates during heating. Nitrates are a class of molecules that contain nitrogen in a form that can be used by living organisms. The discovery adds to the evidence that ancient Mars was habitable for life.
  • Are you getting enough Zinc in your diet?
    Zinc is an important part of the human diet. You get it in Cashews, spinach, beef, shrimp, flax seed, Oysters, garlic, lima beans peanuts, turkey, Salmon, Pork, Brown rice and other foods. These are not listed in any particular order.Zinc, is an important mineral in human health, that appears to affect how the immune system responds to stimulation, especially inflammation, new research from Oregon State University shows.Zinc deficiency could play a role in chronic diseases such as cardiovascular disease, cancer and diabetes   that involve inflammation. Such diseases often show up in older adults, who are more at risk for zinc deficiency.“When you take away zinc, the cells that control inflammation appear to activate and respond differently; this causes the cells to promote more inflammation,” said Emily Ho, a professor and director of the Moore Family Center for Whole Grain Foods, Nutrition and Preventive Health in the OSU College of Public Health and Human Sciences, and lead author of the study.
